The ring is covered in a diamond-based abrasive, which cuts hard materials such as stone, granite, marble, glass, non-ferrous metals, acrylic and plexiglass, yet won’t cut you if you happen to stray into the “blade.” (Gemini says skin bounces off the abrasive where as immovable materials don’t.)

The ring also cuts in all directions — as opposed to one direction with a band saw – which makes shaped cuts easier, and it doesn’t vibrate like a reciprocating saw. The drive belt in Gemini’s saws draws water up to cool and lubricate the cut, so no pump is needed.

One Response to Gemini’s Tile Cutting Ring Saws

Diamond ring saws in this price range are all plastic construction. The gemini3 is considered the best. All ring saws in this price range can do some amazing things with glass and stone. I do stained glass mosaics and do a lot of underwater scenes. Ive taken a piece of white glasss and cut it into brain coral. Ive done palm trees where Ive cut every frond on a coconut palm as a seperate piece of glass as thin as 1/32 inch.
Blades are expensive (about $70) If your a hardcore glass cutter like me you will go through a couple blades a year. The plastic pulleys and rubber belts will need replacing every other year. But theese tools can make cuts that no other tool is capable of.
I bought the Taurus brand. I wish I had bought the gemini3. You can find them as cheap as $320 if you look around. Its a lot for a plastic tool but they do make some amazing cuts.
